Synanceja sp. - a fish which can camouflage itself, changing its colour to match the background. It remains motionless on the bottom where the unwary victim can tread on it. There are 13 venomous dorsal spines on its back which can penetrate even thin-soled shoes, injecting a venom that causes severe localised pain. The pain is best relieved by the application of heat. No deaths have occurred in Australia; 2 poorly-documented deaths have occurred in other countries.
